I apologize; I made a stupid mistake. The notice from confirmation request came from sullivanfamily-request@xxxxxxxxxxxxxxxx and I have the email host in /var/mailman/Mailman/mm_cfg.py set to bullet.espersunited.com because it would not work with just espersunited.com. Is there a way to allow the users of the list to send all list mail (posts as well as subscription confirmations) to espersunited.com instead of bullet.espersunited.com since the confirmation request is sent from espersunited.com so that we could avoid a lot of confusion? -Michael Sullivan-
